Comment-errors

This project is not a full language, but rather adds first-class comments to an existing language: Rust.

It is a proc-macro that hijacks doc comment syntax inside function definition to use them as templates for nicer error-reporting.

The proc-macro source is in comment-errors. comment-errors-test contains a few examples.

Running the example

cargo run -p comment-errors-test

Note, on NixOS I was having issues getting the proc-macro to compile properly and ended up doing:

cargo +nightly run -Ztarget-applies-to-host -p comment-errors-test
